Kenneth Allen McDuff (March 21, 1946 November 17, 1998) was an American serial killer suspected of at least 14 murders. He had previously been on death row from 1968 to 1972. Kenneth Allen McDuff was born at 201 Linden Street in the central Texas town of Rosebud (Falls County), one of four children born to John and Addie McDuff. His father worked as a farmer and mason. McDuff's mother, Addie, was known around their small town as 'The pistol packin' momma' due to her propensity toward violence and habit of carrying a firearm. She has been characterized as domineering by Christopher Berry-Dee, who authored a short biography of Kenneth McDuff as part of his book Talking with Serial Killers. McDuff was known to fire at living creatures with a .22 rifle as a young boy as well as to get into fights with boys older than he was. This led to his acquiring a fearsome reputation in Rosebud, and it was not long before he became known to the local Sheriff, Larry Pamplin.
